DRILL AND CULTIVATOR.

tion, and arrangement of parts, substantially as hereinafter fully setforth, and particularly pointed out in the claims. 7

In the accompanying drawings, Figure 1 is aplan view of our improvedcultivator. Fig. 2 is a rear end view. Fig. 2 is a detail perspectiveview. Fig. 3 is a side elevation with one of the carrying-wheelsremoved. Fig. 4. is a transverse sectional view. Fig. 5 is a detail viewof one of the drills. Fig. 6 is a plan view of a modification. Figs. 7and 8 are detail views thereof. Fig. 9 is a plan view of anothermodification, and Figs. 10 and 11 are detail views thereof.

Referring to the drawings, A designates the drill-frame, the rear endsof the side bars of which are connected by a cross-bar, a, whereon thedrivers seat a is located, and to this cross bar are connected the rearends of two supporting-bars, a a, secured at their forward ends to thefront of the frame.

B is the seed-box, suitably mounted upon the frame A, and in said boxworks an ordinary agitating-roll, 1), upon one end of which is securedapinion or small gear-wheel, b, intermeshing with asecond similar pinionor gear-wheel, b.

O O are two'carrying-whcels loosely secured to their axles, and to thehub of one of said wheels is secured a large pinion or gear-wheel,

I), with which intermeshes a pinion, b, journaled upon an arm,'battached to the axle.- This pinion I) is designed to be thrown in andout of gear with the pinion or gear-wheel b D is a rock-shaft secured tothe frame A, and is provided with a right-angular plate or arm, d, whichis loosely connected to the outer end of the arm To this rock-shaft isconnected alever, d, by means whereof said shaft can be operated.

E designates the series of drill-tooth bars, carrying the teeth at theirrear ends and pivotally secured at their forward ends to a crossbar, 0.Upon the upper edge of each drilltooth bar bears a small grooved roller,E, secured in the lower recessed end of a curved spring-arm, a, attachedat its other end to a cross-bar, 6 of frame A. The spring-arms e aredesigned to hold the drill-teeth down to their work, and areused in lieuof and are an improvement over the ordinary coil-springs.

A slightly curved or bent arm, E is secured to each drill-tooth bar soas to project beneath the same, and the lower inner end of said arm isforked and has loosely secured thereto two small rollers or wheels, E,which occupy a position immediately in front of the drill proper.

To the under side of the crossbar e of the drills is loosely connectedthe forward end of an arm, 6 rigidly secured to the rock-shaft D,whereby by moving said rock-shaft said drills can be raised or lowered,as desired, and at the same time the wheel or pinion If will be thrownin or out of gear, starting or ceasing the agitation of the seed orgrain in the seed- 7 box.

F is a marker, composed of a curved bar, f, to the outer end of which isconnected a bar, f, for effecting the marking, and said marker ispivotally secured on a short rear central extension or stud, f,projecting from the frame A. This marker is designed to rest in and besupported by either one of two curved or U- shaped bars, f f, attachedto the frame A.

G is a centrally-disposed longitudinal rod resting at its rear end in across-bar, g, and to this rod is connected a treadle-bar, g, whereonrest the feet of the driver or operator. To the forward end of this rodG is connected a pinion, g, gearing or intermeshing with a raclebar, 9working in a grooved plate, 9, in front of which is formed a slot orrecess, 9

The tongue H is projected through a loop, h, and its rear end isextended through the slot or recess 9 and connected to the rack-bar 9,whereby by pressing on the treadle-bar g the tongue will be shifted fromside to side, so as to throw the same in the line of draft.

In lieu of the above-deseribed form of mechanism for shifting thetongue, that shown in Fig. 6 may be employed. In this form the rack-barhas a horizontal right-angular portion, I, provided with a centraltongue pro jecting through an aperture of a guide-plate,

f, on the end of the rod G.

A modified form of the drill-bar E is shown in Fig. 7,wherein a singlecutter wheel or disk, K, is employed, located a short distance in frontof the drill-point.

If desired, instead of connecting the arm a of the lever d directly tothe drills, the same can be connected to a rock-shaft, it, which, asshown in Fig. (3, is mounted on the bars a or said rock-shaft can besecured to the under side of said bars, as shown in Fig. 9.

\Ve claim as our invention- 1. As an improvement in grain-drills, thecombination, with the drill-frame, of the inclined rod secured thereto,and having a treadle-bar and treadle at one end, a wheel or pinionattached to the forward end of said rod, the horizontal rack-bar withwhich said pinion engages, and the pivoted tongue connected to saidrack-bar, substantially as shown and described.

2. The combination, with the drill-frame, of the inclined rod securedthereto, and having a treadle-bar and treadle at its upper rear end anda pinion at its lower forward end, the horizontal bar with which saidpinion engages, the slotted guide-plate secured to the front of saidframe, and the pivoted tongue, substantially as shown and described.

As an improvement in grain-drills, the series of springarms a, carryingfrictional rollers in their ends, bearing on the upper edges of thedrill-bars, substantially as shown and described.

In testimony whereof we affix our signatures in presence of twowitnesses.
